The best reason for the use of Albin Pump Hose pumps in this industry is the low maintenance of the pump. This industry readily accepts an average hose life of 1.500 - 3.000 hours in continuous duty and this hose life will provide much lower maintenance costs and repair time than with other pumps. Basic Pump Requirements For operation in an automatic system the following would ...

ABSTRACTEffective disinfection and stabilization of sewage sludge prior to land application is essential to not only protect human health, but also to convince the public of its benefits and safety. A basic understanding of the key factors involved in producing a stable biosolid product is a necessary component to ensuring that effective disinfection and stabilization are achieved. Key stressors ...

Saint-Malo is an extremely attractive and popular seaside resort on the north coast of Brittany in France. Covering 1,400 hectares, the local population of 50,000 increases to 120,000 in the tourist season. One of the distinguishing features of this part of the Channel coast is a very high tidal range – 14 meters from low to high, with a potential impact back through the sewer network. Combined ...

Last week it was announced that Thames Water would be fined a record £20.3million for polluting the body of the River Thames with around 1.4billion litres of raw sewage.The company admitted their offence and accepted the penalty. Read more about this, and hear our thoughts, in our exclusive ...

Two experiments were conducted to evaluate the effect of a sewage sludge-based compost (SSC) on the growth and mineral composition of containerized Pinus pinea L. seedlings. In the first experiment, five different substrates were tested: four binary mixtures of SSC and peat (100% SSC, 75% SSC, 50% SSC and 25% SSC, by volume) without fertilization, and a control substrate (peat-based substrate + ...

Phillip Dempster, Principal Officer, Corporate Resources Property, with East Sussex County Council, said theauthority had first of all approached the local water authority regarding a scheme which would be adopted as a public utility, but in view of the costs involved they looked at other alternatives and decided to approach Mono because of the reputation of their products. The combination of the ...

SimpleTreat 3.1 is the sewage treatment plant (STP) model implemented in the EU framework for the environmental risk assessment of chemicals. The model was originally designed for neutral hydrophobic chemicals, while many substances currently under regulatory scrutiny, are ionisable at environmental pH. Although the model has been adapted to describe ionisation (SimpleTreat 3.1), the fate of ...

As researchers analyze the soils’ ability to absorb discharge, more knowledge is gained about alternatives to septic tanks and standard drain fields that include peat filter systems, constructed wetlands and drip irrigation. ONE out of every four American households currently treat and release wastewater on their own property. Although most people assume that on-site systems are confined to rural ...

The adsorption kinetics and thermodynamics of two anionic dyes (Reactive Brilliant Red K-2BP and Acid Scarlet GR) on the Sewage Sludge Derived Activated Carbon (SAC) were studied by batch adsorption tests. It was found that, for Reactive Brilliant Red K-2BP, four kinetic models, i.e., the pseudo-second-order model, the modified pseudo-first-order model, the pseudo-first-order model, and the ...

Final disposal of sewage sludge is important not only in terms of satisfying the regulations, but the aspect of choosing the optimal wastewater treatment technology, including the sludge treatment. In most EU countries, significant amounts of stabilized and dewatered sludge are incinerated, and sewage sludge ash (SSA) is generated as a by product. At the same time, lime is one of the commonly ...

To examine the performance of a constructed wetland system on stormwater runoff and domestic sewage (SRS) treatment in central east China, two parallel pilot-scale integrated constructed wetland (ICW) systems were operated for one year. Each ICW consisted of a down-flow bed, an up-flow bed and a horizontal subsurface flow bed. The average removal rates of chemical oxygen demand (CODCr), total ...

Problem The high concentration of Industry, Agriculture and People in and around the United States has changed the “nature” of our environment. There are Toxic Metals coming from various metallurgical processes; Plating, Foundry, Smelting, Milling, etc., which are readily determined by Atomic Absorption Spectroscopy (AAS). Volatile Organics from the many Petrochemical-based operations are ...

To evaluate the presence and distribution of the three main viruses (rotavirus, astrovirus, and norovirus) responsible for human acute gastroenteritis in sewerage systems, a one-year study was carried out in Beijing, China. A total of 96 samples of influent and effluents from three sewage treatment plants (STPs) were collected from November 2006 to October 2007. Silica was used to concentrate ...

Leading construction companies Amec and Carillion joined forces in the £172 million project to build ManchesterAirports second runway and turned to Mono to provide a Mutrator sewage pumping system for the new fire station. The Mutrator pumping system consists of two industrial progressing cavity (p.c.) pumps and two M18D macerators. The system was supplied with all interconnecting pipework and ...

The Thames Tideway Tunnel (TTT), is one of the main components of the London Tideway Improvements Programme, designed to capture combined sewer overflows (CSOs) which currently discharge untreated combined sewage into the tidal river Thames. CSO discharges would be stored in the tunnel until there is capacity at Beckton sewage treatment works (STW), to accept, for treatment, pumped sewage from ...

The recycling to agricultural land is an important outlet for sewage sludge and other sludges but it must be controlled in order as to obtain agricultural benefit from the sludge whilst protecting human and animal health and the environment at large. Current practices in Europe are based on the requirements of the 1986 Directive on the use of sewage sludge in agriculture (86/278/EEC). Since that ...

Processing waste discharges, manufacturing effluents and sewage would not normally have been a problem 50 years ago, but the advent of almost unchecked industrial growth the latter half of the last century has created the POTENTIAL for a wide variety of characterized pollutants to enter the environment of any municipality. The toxic METALS are tested by approved State & Federal methods defined in ...

A regional wastewater treatment plant was found to be discharging high concentrations of fecal coliform bacteria in excess of acceptable surface water criteria. An investigation of the sources of those bacteria showed their origins to have been environmental, primarily from a pulp and paper mill. False positive and false negative fecal coliforms were also found and enumerated. These bacteria were ...
